lle il known that l. ALLEN lf. llahnmias, of New laris, Preble county.4 Ohio, have invented a new a ad useful Improvement iu 'trat-lis or loadw-:ys,i'tor the Tse of Motorlropelled Vehicles; and l declare the tol lowing to he an exact description thereot', reference being had to the accompanying drawings, and to the letters of reference marked thereon, which `forni part of this sperilication.

illy inrr-ntion relates to improvements in the torni and construction of tracks or ways alongpublic roads or elsewhere, in a pei-Inanent and e anparatively inexpensive Inanner of concrete, over which automobiles, and specially rmistructed cars nray loe operated either tor pleasure or t'or carrying l asseireewy and tre Among the objects ot this improvement in sueli roadway or tra 'it is, first-to malte possible and practicable its permanent` and eronoinical construction ot' the most durable material tor the purpose for which it is der signed. Helmuth-a track designed for spe ciallv construeled inotor propelled vehicles with rul l er or other elastic tires for regular service in the transportation of freight, pas-V sengers.inails,&e., as well as for private inotor propelled, elastic tired vehicles, such as are non' in eonunon use, which trac-k may he ronstrueted either alongn publie l'iighways or elsewhere, on private right' ot' way, Without relier-eure to the contour ot the `ground, ron'neclinr poi-nts niost directly, thus 'furnishing' rapid'transit to tonniy villages, and outlay of capitai l attain these ohjects lgiy the iorni and manner ot conslru Lion illustrated in the ae- .'oinlninyingr drawing in Aldrich-W Fir'ure i represents a. cross-section of the track, oolistrui :al 'ter vehicles using wheels either singly, as ordinziry automoliilefl, or in pairs as heavy trucks, or specially ronslructed ca hier L a vertical section ot the trarlf, designed tor vehicles usineT wheels singly, as auloniobi es, and shows the adjustmento'l' wheels thereon to the grooves therein.
